Schizophrenic and normal subjects' responses to the Stanford-Binet Vocabulary items, the Wechsler Adult Intelligence Scale (WAIS) Vocabulary items, and the WAIS Similarities items were scored by two methods, one relatively strict and the other relatively lenient. (Editor)

True-false scales were devised to measure anhedonia, the lowered ability to experience pleasure. The scales were Physical Anhedonia (40 items) and Social Anhedonia (48 items). (Editor)

An investigator's method of selecting schizophrenic and control subjects for comparison can assure either a difference or a lack of difference between groups on almost any kind of task that requires a voluntary response. Discusses how researchers should select subjects and the inferences that may reasonably be drawn from studies of schizophrenic…
